This was previously implicitly done in ff_raw_read_header().
Fixes fate tests with pcm input.

avio_size() reports the filesize which returns 0 for /dev/null.
avio_tell() reports the current position.

Also handle errors from avio_tell().

Fixes CID700635, CID700636 and CID732274.

It is not used anymore and is a kludge.

The code shared is not actually shared with anything else.

ff_raw_read_header is used only for this demuxer for video.

The function is used elsewhere and does not belong with the LZO code.

Also use dts instead of pts for deciding where to split fragments.

Avoids memleaks with audio when extended_data is nontrivial and the user
doesn't reset the frame.
Shouldn't have any effect for video for now, but might be useful in the
future.

Also fixes 3 compiler warnings about using uninitialized variables.

Since the requirement for output padding has been lifted, we can
use av_memcpy_backptr() here as well.

The function can return either a parsing error or a memory management
error.

Properly forward mp_decode_layer3 errors, mp_decode_layer1 and
mp_decode_layer2 do not return errors.

This adds support for building on Plan 9 x86-32.  The compat/plan9
directory contains these items:

- replacements for the 'head' and 'printf' shell commands
- wrapper for main() to disable FPU exceptions

Larger required changes to the system are described in the
documentation.
